' The valid range of a Byte variable is 0 through 255.
Dim b As Byte
b = 30
' The following statement causes an error because the value is too large.
'b = 256
' The following statement causes an error because the value is negative.
'b = -5
' The following statement sets b to 6.
b = CByte(5.7)
' The following statements apply bit-shift operators to b.
' The initial value of b is 6.
Console.WriteLine(b)
' Bit shift to the right divides the number in half. In this
' example, binary 110 becomes 11.
b >>= 1
' The following statement displays 3.
Console.WriteLine(b)
' Now shift back to the original position, and then one more bit
' to the left. Each shift to the left doubles the value. In this
' example, binary 11 becomes 1100.
b <<= 2
' The following statement displays 12.
Console.WriteLine(b)
